[Icom] MARS xmt for 756ProII

[Ray, W2EC]

Thanks JV, 

I'm still a bit confused though, referring to the www.dk.mods page:

The instructions for a 756Pro Board Version #2 indicates you remove
diodes D3751, 3752 and 3753.

The instructions for a 756Pro Board Version #03 indicates diode D3751 is
already missing and you have to remove diodes D3752, 3753 and 3754.

The instructions for a 756ProII indicate remove only diodes D3751 and
3752.

From your comments sounds like you do have a 756ProII (not a 756Pro) and
that you removed diodes D3751, 3752 and 3753.

Guess I'll head for the shack workbench and remove that D3753 and see if
the clears up my issues!

Thanks & 73, Ray  W2EC
